He left me for his affair partner - do I have a chance ?

Hello , I will try and keep this as brie … just need some advice

Married for 18 yrs , together for 21 . He is the love of my life , we have 2 teenage kids .
I am very ambitious and career driven , love my family more than anything but did focus too much on my kids and career
He began an affair with his co worker and has now left me for her - he blamed me for our failed marriage. I saw it as an opportunity to restart our relationship, learn and grow but he was too obsessed with the other woman.
What can I do to start the process of recovering from the betrayal and work towards bringing him back home. My kids and I miss him… he feels he is happy and tells everyone we know how happy he is now … he and the other woman have bought a dog together but have not moved in … I need so much help .

Affairs are often fantasy relationships. They exist in a bubble, with the two people sneaking around to be together, they experience just the highs of a relationship but little of the real life things that make real relationships hard. They may be in love but they have no idea what is in store for them when they try to live together.

This might not survive the stressors of the real world. It may take some time for that to happen. Maybe in a few months to a year or so he may realize that leaving you for her was a grave mistake.

Sorry I can’t give you better advice. This is a pretty difficult situation that I think will take some time to resolve.
